In this printing device, replaceable parts can be automatically replaced, further reducing the burden on the worker.
  • the screen mask may be replaced using an exchange frame to which the screen mask is fixed.

  • the screen mask is fixed in an eccentric position toward one side of the outer periphery of the frame, and there is a portion of the screen mask with no margins, so the screen mask can be positioned more reliably on the substrate. In this way, with this replacement frame, printing processes can be more reliably performed in a printing device that replaces the screen mask.
